Well we are not going to be able to change the share names because there are people currently using them the way they are and we are not ready to go live with this script domain wide yet. My boss/network administration says he really doesn't care about the script running on the 98 clients.

I ran that code
? "The value of InGroup(Mapping And Addressing) is : " + InGroup('Mapping And Addressing')
and i got a result of = 1

I change the And to & and got a result of = 0

I believe the actual group name in AD is
Mapping & Addressing.
